Title: Apparatus and method of mounting semiconductor integrated circuit
Inventor: NAKAMURA YUKIO
IPC: H05K3/34
Filed: 1990-02-20
Abstract: PURPOSE:To contrive to improve a productivity by putting a solder in a heat- resisting container with a pipe, by fusing the solder through a heater wound round the outer periphery of the heat-resisting container and by discharging a constant quantity of solder from a nozzle of extra fine diameter provided continuously at the lower part of the heat-resisting container. CONSTITUTION:A solder 4 contained in a heat-resisting container 5 is heat-fused by a heater 6 around the container, air is adjusted and fed from a pipe 7 provided in the upper part, and the pressure of the fed air causes the fused solder 4 to drop correctly by constant quantities from a nozzle 8 of extra fine diameter provided at the lower part of the heat-resisting container 5 successively onto an electrode 2 on a mounted substrate 1 coated with flux so that a solder bump 9 is formed. In this case, a solder discharge quantity is adjusted from the thickness of a photoresist 3 and the size of the electrode 2 and the granular solder bump 9 is formed immediately from the point of time when the solder drops. Thus, the solder bump of constant height is formed and granulated simultaneously with the discharge so that one process is omitted.

Title: Heat pump type bath water heating device
Inventor: OKABE MASAAKI
IPC: F24H1/00
Filed: 1989-02-17
Abstract: PURPOSE:To provide an economical heat pump type bath water heating device by boiling bath water with use of a heat pump at a first predetermined time before set bathing time, and supplying a heater with electric power at a second predetermined time after the elapse of certain time for simultaneous use of the same with said heat pump. CONSTITUTION:Once a bathing time is set, it is first judged whether or not present time is before the set bathing time. If yes, present hot water temperature Tw is detected and compared with hot water temperature set value Ts, and if Tw>=Ts, an output is issued which instructs a circulation pump 12 to be on, and a compressor 21 and an electric heater 3 to be on. If Tw<Ts, the circulation pump 12 and the compressor 21 are turned on to heat the hot water temperature to Tw=Ts. If the present time is before the set bathing time after the elapse of certain time, and if the present hot water temperature successively satisfies Tw<Ts, the electric heater 3 is turned on, and the heat pump and the electric heater 3 are both employed to heat the hot water temperature to Tw=Ts. Once the hot water temperature satisfies Tw=Ts, the electric heater 3 is prevented from being again turned on in the bathing time zone.

Title: Underwater noise isolating structure
Inventor: SATO RYUICHI
IPC: G01M10/00
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To reduce the noises propagated in a circulating stream and measure the small noises of a measured object by providing a reinforcing member on the outer periphery of an acoustically soft support tube such as a rubber tube having a specific diameter against the underwater wavelength of the noises to be isolated via the outside air between them, and storing the required number of the support tubes determined by the water supply quantity in unit time in a pressure reinforcing tube. SOLUTION: When water is supplied or fed through an elastic support tube 101 determined with the size of its internal diameter according to the upper limit of the wavelength of the noises generated by a water supply device, the noises of the motor of the water supply device are cut off and are not propagated in a circulating stream theoretically. Since the desired water supply quantity (water supply pressure) cannot be obtained by only one elastic support tube 101, a required number of the support tubes 101 are provided in a pressure reinforcing tube 100.  If the elastic support tubes 101 are kept in touch with each other, the acoustically soft condition is not satisfied, therefore a reinforcing member 102 such as a metal or fiber net is provided around each elastic support tube 101, and the outer periphery of each elastic support tube 101 is invariably kept in contact with the outside air.

Filed: 1988-02-23
Abstract: PURPOSE:To eliminate need of high-speed rotation of a cleaning brush by using the conductive cleaning brush as a cleaning member which removes fine coloring particles remaining on an image carrier and applying a bias voltage having a polarity opposite to the charging polarity of fine particles. CONSTITUTION:A conductive brush roll 12 brought into contact with a photosensitive body 1, a metallic roll 13 brought into contact with the roll 12, and a scraper 14 brought into contact with the roll 13 are provided. After transfer, toner T remaining on the photosensitive body 1 is mechanically scraped by the cleaning brush which is brought into contact with the photosensitive body 1 and is rotated in the direction of an arrow B. Simultaneously, toner electrified with a negative polarity by a positive bias voltage applied to the brush is electrostatically attracted to the surface of the brush and is removed from the photosensitive body 1 to clean the photosensitive body 1. This toner is electrostatically attracted to the metallic roll 13 and is scraped by the scraper 14. Thus, high-speed rotation of the brush is unnecessary.

Filed: 1984-03-02
Abstract: PURPOSE:To attain high speed data transfer while relieving the load of a CPU due to the intervention of a software interruption processing by realizing a data transfer function through the character control by means of the hardware. CONSTITUTION:In case of an input/output request for end of transmission and end of reception, the data transfer processing by the character control between a transmission buffer register 100-1 or a reception buffer register 100-2 and a data memory 104 is conducted without intervention of the software.

Title: Method for hot-rolling dead soft steel
Inventor: YAMASHITA MICHIO
IPC: B21B45/00
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of seam flaw of a product by heating the slab of dead soft steel in a heating furnace at a temp. of less than a specified temp. and executing rough rolling after transforming the whole of outer layer part in the end part of the width end part into α-phase. SOLUTION: To dead soft steel which is rough rolled under the ordinary descaling conditions, the heating temp. of the slab is regulated at <1000 deg.C. In this way, generation of seam flaw in a product is suppressed. In such a case, the whole of the outer layer part in the end corner parts of the width is transformed into α-phase. Consequently, it is necessary to positively strongly cool the end parts of the width from a state where only the corner parts of the width end become the α-phase, but a method by which strong cooling is executed by adjusting the quantity of water for descaling just before each rough rolling is desirable from various viewpoints. Specifically, the heating temp. of the slab is taken as 1100-1150 deg.C and the quantity of water for descaling is taken as the degree two times, for example, the ordinary quantity, it is executed to jet the water from the upper and lower sides of a material or the like.
